The invention provides an anti-circulation method for rail transit traction power supply. The anti-circulation method for rail transit traction power supply comprises the following steps: S1, according to a power flow calculation principle, verifying whether the rail transit traction power supply system has an external droop characteristic, and the verification process is as follows: (1) based on the power flow calculation principle, obtaining an output active power expression and an output reactive power expression of any traction substation i, namely a formula (1) and a formula (2); according to the anti-circulation method for rail transit traction power supply provided by the invention, generation of circulation can be suppressed, so that the problems of system current distortion, additional loss increase of the system and influence on the overall performance of the system can be solved.
本发明提供一种用于轨道交通牵引供电防环流方法。所述用于轨道交通牵引供电防环流方法包括以下步骤:S1.根据潮流计算原理,验证轨道交通牵引供电系统是否具有外下垂特性,验证过程如下所示:(1).基于潮流计算原理,可得任一牵引变电所i的输出有功和无功表达式,即为公式(1)和公式(2)。本发明提供的用于轨道交通牵引供电防环流方法可以仰制环流的产生,致使可以解决系统电流畸变,增加系统额外的损耗以及影响系统整体性能的问题。
